Thanks guys I'll do another compression check and go from there.

My Subaru 2.5 is over heating only when driving. I've bled the cooling system, replaced the thermostat, top and bottom hoses, radiator cap and flush the radiator but still over heat.Cooling fan are working. I let the car run sitting in the driveway for over a hour and it went to normal temp with fans running but didn't over heat at all but when I drove it for about 20 minutes it pushed the coolant into the overflow and temp went to the hot mark. Can anyone tell me what to do next. I also did a compression check which was normal range....
